Order 15616.
1302 conjugacy classes of subgroups.
The subgroup lattice has 288 nodes — too large to display as a diagram.
Splittings G = N ⋊ H with N normal; H ≅ G/N.
| N | H ≅ G/N | type |
|---|---|---|
| 2. #21445902 | C2 | semidirect |
| 3. #21445899 | C2 | semidirect |
| 4. #21445558 | C2 | semidirect |
| 5. C2×#16839531 | C2 | semidirect |
| 165. C61 | #20695 | semidirect |
By isomorphism type — maximal subgroups of the same type appear once, whether or not they are normal.
